摘要

Neurodegenerative diseases such as ischemic stroke leads to severe changes in the pattern by which limb movements are completed during skilled forelimb movements. Assessments of such movements in animal models are carried out using tests like reach to grasp task. Rats acquire the reach to grasp task through training and the skill is retained over long period. Learning of a skill is affected by various factors like attention, knowledge of the results, prediction etc. Current study investigates the role of prediction in the improvement of performance in reach to grasp task in rats. Providing a challenging environment with the randomized pellet size has reduced the prediction ability of the rats in execution of movements.Current study shows that the prediction of pellet size has a critical role in reach to grasp performance and the rats are not able to form a unified movement strategy to accommodate any of given size of pellets.
